What is wrong with my photorealistic procedural chocolate texture?
This node setup isn't really the best to use if you want the crumbly scratched look, if you look at the image that the node setup was posted with the chocolate is very smooth.
You can adjust the black and white ColorRamp going into the roughness of the material to get some smears to show, but it won't really get you any farther than that.
I suggest you make your own material, and use surface imperfection textures for the roughness and bump, that will give you the scratched up look you want.
